25A 2P DC Circuit Breaker For Solar Energy Easy to Install TOMC7-63DC/2/C25 Features: The current specifications range from 1 amp to 6 amps for low current, 10 amps to 40 amps for medium current, and 50 amps to 63 amps for high current All comply with international IEC standards, and the products are usually suitable for photovoltaic solar power generation systems, fusion systems, and storage systems In a set of solar combiner boxes, in addition to DC circuit breakers, DC fuses, DC surge protectors, and DC isolators are generally installed To avoid personal electric shock accidents, leakage protection switches will also be installed The function of 2P DC MCB is actually the same as that of ordinary MCBs There are short-circuit protection, overload protection, and general circuit braking function The main difference is that the DC MCBs use direct current (DC), and the direct current (DC) is a unidirectional flow of electric charge Direct current can flow through conductors such as wires, but it can also flow through semiconductors, insulators, or even vacuum-like electron beams or ion beams The current flows in a constant direction, which is different from the curvilinear movement of alternating current (AC) Specifications: Brand: Tongou Model: TOMC7-63DC/2/C25 Pole No: 2 Rated voltage: DC12V-250V Rated current(A): 25 Rated short-circuit capacity(lcn): 6kA Rated frequency: 50/60Hz Energy limiting class: 3 Rated impulse withstand voltage: 6.2kV Electro-mechanical endurance: ≥ 6000 Connection terminal: Screw terminal / Pillar terminal with clamp Connection capacity: Rigid conductor up to 25mm² Fastening torque: 2.0Nm Installation: On symmetrical DIN rail 35mm / Panel mounting Ambient air temperature for operation: -35°C to +70°C Ambient air temperature for storage: -40°C to +85°C Package Included: 1 x DC Circuit Breaker
